Fiat builds off its 500 by Gucci hatchback buzz and announces the release of its topless version. The 500C by Gucci will be available in white or black, with the same exterior and upholstery as the 500. The only notable difference between the two is that the Gucci pattern on the 500C was lifted from its side and placed on the convertible top. Exactly how much cooler is the topless version? About $5k cooler. You can pre-order a 500C by Gucci for $28,900 compared to the $24,000 price tag of the 500.
